NOTE
< IMAGE PERSISTENCE >
Please be aware that LCD Technology may experience a phenomenon known as Image Persistence. Image Persistence
occurs when residual or “ghost” image of a previous image remains visible on the screen. Unlike CRT monitors, LCD
monitors’ image persistence is not permanent, but constant images being displayed for a long period of time should be
avoided.
To alleviate image persistence, turn off the monitor for as long as the previous image was displayed. For example, if an
image was on the monitor for one hour and a residual image remains, the monitor should be turned off for one hour to erase
the image.
As with all personal display devices, MITSUBISHI ELECTRIC recommends displaying moving images and using a moving
screen saver at regular intervals whenever the screen is idle or turning off the monitor when not in use.
Please set “POWER SAVE”, “SCREEN SAVER”, “DATE AND TIME” and “SCHEDULE” functions to further reduce the risk of
Image persistence.
< For long life use of Public Display >
Image Sticking of LCD Panel
When LCD panel is operated continuously for long hours, a trace of electric charge remains near the electrode inside LCD, and
residual or “ghost” image of previous image may be observed. (Image Persistence)
Image Persistence is not permanent, but when a fi xed image is displayed for a long period, ionic impurities inside LCD are
accumulated along the displayed image, and it is observed permanently. (Image Sticking)
Recommendations
For preventing the fast transition to Image Sticking, and for longer life usage of LCD, the following are recommended.
1. Fixed images should not be displayed for long periods of time, and changed to another images with short cycle.
2. When the monitor is not in use, please turn it off using the remote control, use the Power Management Function or use the
Schedule Function.
3. Reducing the environmental temperature is effective for long life use.
When a Protection board (glass, acrylic) is installed over the LCD surface, enclosed into the box / wall, or the monitors are
stacked, please utilize the temperature sensors inside monitor.
To reduce the environmental temperature, the monitor should be set Low Brightness or Cooling Fan “ON” by using the
Screen saver Function.
4. Please use “Screen Saver Mode” of monitor.
< HOW TO SETUP SCHEDULE >
Using the “SCHEDULE” function allows you to set up to seven different scheduled time intervals when the LCD Monitor will be
activated.
You can select the time the monitor turns on and turns off, the day of week the monitor is activated, and which input source the
monitor will use for each scheduled activation period. A check mark in the box next to the number of the schedule
indicates that the selected schedule is in effect.
To select which schedule to set, use the up/down arrows to move the number (1 to 7) of the schedule.
Use the (+) and (-) buttons to move the cursor horizontally within the particular schedule. Use the (
) and ( ) buttons to
increase time and select input port. The “SET” button is used to make a selection.
If you create a schedule but do not want to use a power on time, select “--” in the “ON” time slot.
If you do not want to use a power off time select “--” in the OFF time slot.
If there is no input selected (“--” showing in the input spot) the input from the previous schedule will be used.
The selection of EVERY DAY within a schedule takes priority over other schedules that are set up to operate weekly.
When schedules are overlapping, scheduled Power ON time has priority over scheduled Power OFF time.
If there are two schedules programmed for the same time, then the highest numbered schedule has priority.
When the “OFF TIMER” (see page 29) is set, the “SCHEDULE” function is disabled.
